HOLLOW BUILDING TILE.

son and State of Alabama, have invented certain. new and useful Improvements in.

Hollow Building Tiles, of which the following is a specification; p

My invention relates to a hollow building tile or block, and has foritsobject to produce in. a single structure a tile which can be readily subdivided at the plant either be? fore or after baking, or if baked whole can be broken apart-on the job to convertit into the various special'tiles normally required for construction purposes'in closing courses and finishing corners, doors, windowsand chimney openings. f 7 A In hollow tile construction, in addition to the regular standard blocks, it is now necessary to manufacture and carry in stock .the following special blocks, namely, header blocks for course or closure s,right and left hand whole jamb blocks, right and left hand half jamb blocks and'whol'e double jamb l s q The present practice'is to buy a certain percentage of each of these special blocks along with the estimated requirements of standard-blocks, thus making it necessary ,for the manufacturer to make and keep in stock a large variety ofspecial blocks and for the builder to order his estimated requirementsof each special block, and in addition thereto it complicates the filling of orders and increases thebreakage in transit as these special tiles are irregular and much more liable to breakage. 1 I have conceived that a great advantage will accrue to both 40 manufacturer andconsumer if a single integral block can be practically;-manufactured in such shape and w th such'openmgs therethrough and'wi'th such weakened lines or scoring thatthe mason on the job; can

readily convert it into-any one of the vari-- ous'typ'es of special blocks that are normally required, without affecting its availability as a standard block. My present invention cover su h eblock. which presents no .difi ultie Application filed February 1?, 1921. SerialNo. 445,693.

"Similar reference numerals refer to similar parts throughout the drawings. Z 1 I As illustrated, Fig. 1 shows .asection of the clay column asfldelivered fromthe die and which when dried and baked forms a whole building tile or bloclrwhich-has a faced outer or front wall 1 and a scored inner or'back wall 2-connectedby faced parallel end walls 3 and'interposed'center partition walls 4 and 5 andend partition walls .6; and 7. The Walls 3,, 4, 5, 6 and? are all parallel and extendin vertical planes atright angles to the front and rearwalls of the block. The partitions 6 and 7 are disposed closer to their respective adjacent end wall than to .the adjacent middle partitions 41 or 5,?and the latter partitions are spaced equi-distantly from,

Figs Sand 4 illustrateright and1e-ftha1f longitudinal webs 9 and the partitions? and [T1 7 are connected respectively ;to their, ad'- jacent end walls 3 by the vertical longitudinal partitions 10 which are disposed close to the-frontwall1'ofthe'bl-0cki @The end walls are Provide .011 he r; inside fa h'ei he r or both scoring or fracture lines 11 extending from top to bottom in line with the rear edge of the partitions 10, and the rear wall 2 is likewise provided with either or both scoring or fracture lines 12 extending from' top to bottom in line with the. outer face of the partitions 6 and 7. The partitions and the scoring or fracture lines are so arranged that when the block is broken along the center fracture'lines 8we have two standard half blocks, as shown in Fig. 2, suitable for header course or closure, and the scoring llnes 11 and 12 are so arranged that, when the half block is fractured along these lines we have a standard right or left half jamb. Obviously when the block is not broken into halves either end of; the blockmay be fractured along the lines 1-1, 12 to produce a whole jamb block, or both ends may be broken away toform a double jamb block. Any half'or whole jamb produced as above may be used either right or left hand as block, and is readily convertible into any special building block normally required.

My invention in its broadest aspect covers any such arrangement of cells and scoring in the clay column, as dischargedqfrom the die, as will permit the tile or blocks formed therefrom either before or afterbaking to be subdivided into any one or all of the vari ous types of standard 1' ambiblocks, and obviously when it is intended'to subdivide the blocks into any particular jamb block, any scoring or cellular arrangement unnecessary to'th'at end can be dispensed with; When I- refer to building blocks or tiles in the ap-,

pended claims, I mean to include in, such termsthe blocks as formed by subdivisions of the clay column regardless of whether suchare to be broken intojamb blocks before or after baking.

This invention is not intended to be re-V stricted in scope to the specific embodiments shown, but contemplates such modifications as come within the spirit and scope of the 7 claims.
